The COVID-19 pandemic has dramatically changed the way children learn, play, and interact with their surroundings. One of the lesser-discussed side effects of this shift is the potential increase in myopia (nearsightedness) in children. As schools transitioned to online learning and children spent more time indoors, there was a significant change in their visual habits, which has raised concerns among eye care professionals. In this blog, we will explore how the pandemic has impacted myopia development in children, the factors contributing to this increase, and what can be done to prevent and manage the condition.
Myopia, or nearsightedness, is a common refractive error in which distant objects appear blurry while close objects can be seen clearly. It occurs when the eyeball is too long or the cornea has too much curvature, causing light entering the eye to focus in front of the retina. Myopia tends to develop during childhood and can progress as the child grows, leading to higher degrees of nearsightedness.
The pandemic has brought about several changes in children’s routines, particularly the increase in screen time and reduction in outdoor activities, which have contributed to the rise in myopia cases. Below are some of the key factors that have played a role:
With the sudden switch to online learning and virtual classes, children have spent significantly more time in front of screens. This includes not only schoolwork on computers or tablets but also leisure time spent on video games, social media, and watching television. Prolonged screen time, especially at a close distance, has been linked to an increased risk of developing myopia.
Before the pandemic, children had more opportunities for outdoor activities like playing sports, walking, and spending time in natural sunlight. Research has shown that spending time outdoors, especially in bright natural light, can help slow the progression of myopia. However, lockdowns and social distancing measures limited children’s ability to engage in outdoor play, leading to a reduction in protective outdoor exposure.
With social isolation and limited outdoor interactions, children’s daily routines became more sedentary, which not only affected their physical health but also their eye health. In addition, the stress and anxiety brought about by the pandemic, particularly from prolonged isolation, may also contribute to the worsening of myopia in children.
Myopia is not just an issue of blurry vision; it can have long-term consequences. Children with myopia are at higher risk for developing severe visual impairment later in life, especially if the condition continues to worsen during their growing years. High myopia is associated with a greater risk of complications such as:
Therefore, early detection and management of myopia are crucial to prevent these serious long-term consequences.
While there is no way to completely prevent myopia, there are several steps that parents can take to slow its progression and protect their children’s vision:
Make it a priority for children to spend more time outside. Studies have shown that just two hours a day of outdoor time can help reduce the risk of developing myopia or slow its progression. Sunlight exposure is essential, as it helps the eyes relax and reduces the strain caused by prolonged near work.
With online learning still a part of many children’s lives, it’s important to find ways to limit screen time outside of school hours. Encourage activities that don’t require screen use, like reading books, arts and crafts, or playing games outside.
Encourage children to follow the 20-20-20 rule, especially when they are using screens. Every 20 minutes, they should look at something 20 feet away for at least 20 seconds. This simple habit can reduce eye strain and fatigue.
Ensure that children have adequate lighting while reading or studying. Poor lighting can increase eye strain and contribute to the progression of myopia. Bright, indirect natural light is ideal, but if artificial lighting is used, make sure it is not too harsh or dim.
Eye care professionals have been closely monitoring the impact of the pandemic on children’s eye health. Several approaches are being used to diagnose and manage myopia:
Routine eye exams are crucial for detecting myopia early, especially since it often develops unnoticed. Children should have regular eye exams to check for myopia, especially if they are experiencing blurry vision or if there is a family history of refractive errors.
For children diagnosed with myopia, several treatment options are available to slow the progression:
Eye care professionals are educating parents and children about the importance of eye health, including taking regular breaks, reducing screen time, and engaging in outdoor activities. Awareness campaigns and resources are helping families understand the long-term benefits of preventing myopia progression.

The COVID-19 pandemic has certainly impacted children’s visual health, with a noticeable rise in myopia cases due to increased screen time and reduced outdoor activities. However, by taking proactive steps—like encouraging outdoor play, reducing screen time, and scheduling regular eye exams—parents can help mitigate the effects of myopia and preserve their child’s vision.
Remember, the earlier myopia is detected, the more effective the treatments will be in slowing its progression. Make eye care a priority and ensure your child’s vision remains clear and healthy for years to come.
